SPINDLE-BEARING.

Specification of Letters Patent.

Patented NOV. '7, 1911.

To all whom it may concern:

Be it known that I, CHARLES K. SALIs- BURY, a citizen of theUnited States, residing at Milwaukee, in'the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Spindle-Bearings, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to improvements in spindle-bearings for use in cream separators or other high speed machines which require a certain amount of play in such bearings in order to takeup and .overcome slight inaccuracies of balancing, and its object is to provide a new and improved yielding spindle-bearing for the shaft on which the bowl of the cream separator is mounted, or for shafts in other high speed mechanism, which shall have a proper degree of play and in which the amount of play of such bearing may be regulated so that the same bearing may be used with shafts carrying bowls of different sizes and weight.

Another object of this invention is to provide new and improved oiling mechanism for such spindle bearings.

Another object of my invention is to improve such spindle-bearings in sundry details hereinafter set forth.

In the drawings :Figure 1 is a side elevation, partly in vertical section, of a portion of the casing or frame of a cream separator showing vmy device in position. Fig. 2 is an enlarged detail, being a vertical section of the bearing showing, however, part of the bearing proper in elevation. Fig. 3 is an enlarged detail, being a top or plan view of the parts shown in Fig. '2. Fig. 4 is an enlarged detail, being a section on line 44 of 2. Fig. 5 is an enlarged detail, being a vertical section of the adjustable pressure ring and spring carried thereby.

F ig. 6 is a top or plan new of said pressure ring. Fig. 7 is a perspective view of the spring which is mounted in the adjustable pressure ring. v

Referring to the several figures of the drawings, in which corresponding parts are indicated by like reference characters, 8 indicates the frame work or casing of the machine on which is formed the bowl casing 9. 10 indicates the separator bowl which is mounted upon the shaft 11 whose lower end issupported upon a suitable bearing, as 12, mounted in the casing. The shaft may be driven in any well known manner, preferably by a worm 13 on the shaft 11 driven by worm-gear 14 which, in its turn, is driven by other gearing as by gear 15 mounted on shaft 16 which may :loe driven in any suitable way. These parts are not further illustrated or described because they may be of any approved form and description. It will be understood, of course, that the bowl 10 is provided in its interior with suitable liners or other devices for skimming the milk. So far as the bowl itself and the skimming and delivering features, connected therewith, are concerned they may be of any approved type and, forming no part of my present invention, are not illustrate-i or described as they will be readily understood by those skilled in the art.

17 indicates a plate'which is preferably separate from and secured to the bottom of the bowl casing 9 as is best shown in Fig. 1. It is preferably thus made a separate piece for purposes of mechanical construction, but of course could be formed integral with the bottom of the bowl casing 9 if desired. The plate 17 is provided with a circular opening in which the other parts hereinafter described are mounted, and from the central openin depends a downward projecting circular g ange 18. .The circular opening is provided at its top with an interior screw threaded portion 19. The lower end of the downward projecting flange 18 is turned inward and downward at 20 so as to form a shoulder whose upper interior surface 21 slopes downward and inward. This surface may be either straight beveled, or slightly curved so as to afford substantially a balland-socket bearing for the sleeve 22, which is the spindle-bearing proper, in connection with the other parts hereinafter described. This sleeve 22 is centrall 1 bored with a ciroular opening 23 to a 0rd a journal in which. the shaft 11 revolves. At'a suitable distance between its ends the sleeve 22 is provided with a peripheral shoulder 24 which is rounded in section, as is best shown in Figs. 1 and 2 and, when the sleeve is in I into the screw threaded position, supports the sleeve on the upper surface of the shoulder 21 ofthe flange 18 and forms substantially a ball-and-socket bearing. The lower end ofthe sleeve 22 is provided with aperipheral shoulder 25.

26 indicates a strip of felt or other oil absorbent material whichin the construction shown is in the'form of a tube mounted upon the exterior surface of the sleeve 22 above the shoulder 25 and extends upward around the peripheral shoulder 24 to near the top of the sleeve, as is best shown in Fig. 2.' This piece of oil absorbent material is eld in placein any suitable manner, as by spiral spring 27 (see Fig. 2).

28 indicates a, fixing pin which is screwed into theshoulder 24 of the sleeve 22 with its outer end projecting therefrom so as to engage a slot 29' in the inward sloping portion of the flange 18, serving to hold the sleeve against rotation in the flange, but with sufficient play to allow free movement of the sleeve in said flange.

30 indicates a bearing-ring whose lower. interior surface is beveled, as is best shown in Fig. 2, and which slips down inside the central opening of the plate 17 outside of the sleeve 22 and the felt material 26, as is best shown in Fig. 2 and when this bearingring is held in position as hereinafter described, it coiiiperates with the sloping shoulders of the an e 18 to form a universal bearing for the s oulder 24 of sleeve 22.

'31 indicates a pressure ring which is screw threaded upon its exterior so, as to screw prortion 19 'in the opening in the plate 17. he outeredge of this ring is provided with a series of scal- I lops or indentations 32 which are adapted to be engaged by a screw. 33 when it E screwed into position into a suitable screw threaded opening in the plate 17 and flange 18. The screw 33 being removed, the ring 31 may obviously be screwed into any desired position in the opening and then locked in place by the insertion of the screw 33.

34 indicates a sprin which is composed of a piece of spring-wire bent in a circular form and also at opposite oints, as 3536, bent'downward so that w en the spring is mounted in a suitable groove 37 on the lower. surface of the adjustable pressu're ring 31,." as indicated in Fig. 5 and in dotted lines in Fig.6, these downward projecting portions 3536 will project below the lower surface of the ring, and, when the parts are in position, bear upon the upper surface of the bearing ring 30.

. of oil openings 38 which open upon the ex- The sleeve '22 is provided with a plurality terior of the sleeve 22 above the shoulder 24 and pass downward and inward so as t0 open into a peripheral groove 39 in the interior of the sleeve. By means of these openings and groove oil will pass from the oil-absorbent material into the interior of the sleeve and oil the opening in which the shaft is journaied.

40 indicates a plurality of oil openings which open upon the exterior of the sleeve 22, above the shoulder 25, and, extending downward and inward, open into a peripheral groove 41 on the interior of the sleeve 22 near its lower end. Oil from the absorbentmaterial will, of course, pass through these openings into the sleeve and further oil the journal bearing. Oil may be supplied to the upper openings in any appropriate 'manner. In the construction shown, oil will be supplied to the felt by being splashed up from oil box 42 in the bottom ofthe casing 8 by the worm wheel 14 as is indicated in Fig. 1. In whatever Way the oil is supplied to the felt, the felt will become saturated, and the slight vibratiolr" of the hearing when the bowl is in rapid revolution will press the oil from the felt throu h the oiling openings into the interior 0 the bearing.

In putting the parts together, the sleeve 22 with the oil absorbent material in place is inserted into the opening in the plate from the top, the rounded shoulder supporting the bearing on the inward projecting portion of the flange 18. The bearing ring 30 is then placed in position as above described and the adjustable ring 31 is screwed into position with the spring bearing upon the upper surface of the ring 30 sothat the sleeve is held in position, but with sufiieient play on account of its substantial ball-and-socket adjustment to allow the slight vibration neces sary in machines of this character. It will g 31 is screwed the greater will be the ten be obvious that the farther down the rin sion upon the spring and the more firmly ring 30 will be pressed against the felt surrounding the shoulder 24 and the less free will be the movement of the sleeve in the bearing. By this means, the spindle of course always being of the same diameter suitable to journal in the sleeve, bowls varying inweight and size may be mounted in the same bearing, the lighter and smaller bowls requiring a less pressure on the spring than do the heavier andlarger ones, in order to secure the proper freedom of movement. It will also be obvious in the above description that exactly the ri ht degree of pressure of the spring 34 may e secured by means of the screw threaded re ssure ring, whereby the sleeve is held yieldingly against upward movement iii its socket whereby the spring has a constant tendency to prevent lateral movement of the spindle and to cen- I ter it again when moved out of normal posiplace, as above described, the bowl is placed in position from above with its spindle journaled in the sleeve as shown and described ill) and the machine is ready for operation.
